Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a steering knuckle structure adapted for use in large-tonnage automotive steering axles. Background Technology

[0002] The steering knuckle is one of the main components of a car steering axle. It enables the car to drive stably and transmit driving direction sensitively. The function of the steering knuckle is to bear the load of the front of the car, support and drive the front wheels to rotate around the kingpin to steer the car. When the car is in motion, it bears variable impact loads, so it is required to have high strength.

[0003] Most steering knuckles currently available are integral structures. The steering knuckle shaft has low strength and is prone to breakage when the car is in motion. Furthermore, the integral structure of the steering knuckle makes disassembly and assembly difficult when it is assembled with the kingpin, which is not conducive to maintenance. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a steering knuckle structure.

[0005] The technical solution provided by this utility model is: a steering knuckle structure, which is characterized in that it is composed of a steering knuckle shaft, a steering knuckle shaft seat, a locating pin, a steering knuckle support, a hexagonal head bolt, and a flat washer; the steering knuckle shaft and the steering knuckle shaft seat are press-fitted together by an interference fit, the steering knuckle shaft seat is positioned with the steering knuckle support by the locating pin, and the steering knuckle shaft seat, the locating pin, and the steering knuckle support are connected together by the hexagonal head bolt and the flat washer.

[0006] Furthermore, the steering knuckle shaft and the steering knuckle shaft seat are separate structures, which are press-fitted together by an interference fit with an interference amount of 0.2.

[0007] The beneficial effects of this utility model are: 1. Simple structure: The steering knuckle shaft and steering knuckle bearing are separate structures, and the steering knuckle bearing has a simple structure and simple casting process; 2. High strength: The steering knuckle shaft is made of high-performance materials, which improves the strength of the steering knuckle and enhances its load-bearing capacity; 3. Low cost: The steering knuckle shaft and steering knuckle shaft seat are separate structures, which makes the casting model simple and the cost low. 4. Easy to disassemble and assemble: The steering knuckle bearing and steering knuckle support are separate structures, making disassembly and assembly simple when assembling with the kingpin.

[0008] Figure 1 This is a schematic diagram of the external structure of this utility model; Figure 2 This is a schematic diagram of the structure of this utility model.

[0009] In the diagram, 1 is the steering knuckle shaft, 2 is the steering knuckle shaft seat, 3 is the locating pin, 4 is the steering knuckle support, 5 is the hexagonal head bolt, and 6 is the flat washer. Detailed Implementation

[0010] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings.

[0011] like Figure 1 , 2 As shown, a steering knuckle structure comprises a steering knuckle shaft 1, a steering knuckle seat 2, a locating pin 3, a steering knuckle support 4, a hexagonal head bolt 5, and a flat washer 6. The steering knuckle shaft 1 is made of high-performance material, which can improve the strength of the steering knuckle. The steering knuckle shaft 1 and the steering knuckle seat 2 are separate structures, which are press-fitted together by an interference fit and welded together, with an interference of about 0.2 mm. The steering knuckle seat 2 and the steering knuckle support 4 are also separate structures. The steering knuckle seat 2 is positioned to the steering knuckle support 4 by the locating pin 3, and the steering knuckle seat 2, the locating pin 3, and the steering knuckle support 4 are connected together by the hexagonal head bolt 5 and the flat washer 6.

[0012] This utility model discloses a steering knuckle structure. During operation, the steering knuckle is connected to the upper steering knuckle arm and the lower steering knuckle arm via upper and lower kingpins, respectively. Rotating the upper and lower steering knuckle arms causes the steering knuckle to rotate around the kingpins, thereby enabling the vehicle to steer. The steering knuckle shaft is connected to the wheel hub via bearings, transmitting the vehicle load to the tires and the ground through the wheel hub, thus having the function of bearing the load of the front of the vehicle. When the car is in motion, it bears varying impact loads.

[0013] It should be understood that any technical features not described in detail in this specification belong to the prior art. Although the embodiments of this utility model patent have been described above in conjunction with the accompanying drawings, this utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make more forms under the guidance of this utility model without departing from the spirit and scope of protection of this utility model and the claims, and these all fall within the protection scope of this utility model.
